Dennis police today released a security photo from a Dennisport liquor store that was robbed by a masked man at knifepoint Monday night.

"We're putting out the picture in hopes that somebody will recognize that sweatshirt," said Dennis police Capt. William Monahan in an interview today. "I think that it's a distinctive enough sweatshirt that somebody may be able to recognize it"

A image taken from security camera footage shows a lone male in a ski mask, black pants and a black-hooded sweatshirt, which has a red-colored oval emblem on the front and a smaller red-colored emblem on the right rear shoulder.

Police responded to Marine Package Store on Route 28 in Dennisport at about 7 p.m. Monday after receiving a call reporting an armed robbery, a Dennis Police Department statement said.

The man, who was described as approximately 5 feet 10 inches in height with a thin build, displayed a knife to the cashier, which he carried in his left hand, a Dennis police statement said.

The suspect left with an undisclosed amount of cash.

Police canvassed the area, speaking to anyone who possibly fit the suspect's description, but came up empty.

Investigators are also trying to identify a man who security footage from a different store shows was in the area at the time of the robbery, Monahan said.

Police currently have no suspects and are still investigating the robbery, Monahan said.
